[Lymphocele as a complication of renal transplantation].

Lymphoceles are a complication of renal transplantation surgery. The source of this lymphatic collections is the lymph draining through the lymphatic vessels located in the transplanted kidney sinus and surrounding the iliac vessels of the receptor. The main etiological factor is the surgical technique used when dissecting these structures for graft placement. Several factors have been suggested as favouring their occurrence, acute rejection being highlighted as one. This paper reviews a series of 517 renal transplantations performed in our service, with a lymphocele incidence of 5.2% (28). Using a log regression model, the influence of age, sex, time in dialysis, presence of tubular acute necrosis in the graft following placement, acute rejection and immunological regime, for the appearance of lymphocele were analyzed. Age and lack of acute tubular necrosis were the only two factors selected by the model. Also, clinical signs and symptoms as well as therapy instituted were analyzed, emphasizing that puncture-drainage and instillation of iodine povidone was 100% effective.

[Is radical surgery indicated in patients with infiltrating bladder carcinoma and involved regional lymph nodes?].

To evaluate the efficacy of radical vesical surgery in Infiltrant Vesical Carcinoma affecting the regional nodes, a retrospective study of a group of 75 patients who underwent radical cystectomy and lymphadenectomy was conducted. Based on the degree of node affectation patients were classified as follows: 49 pN(-) (65.3); 22 pN(+) (29.3); and 4 pN(x) (5.3) in which the pathological anatomy was inconclusive. In the pN(-) group, 8 (8.16%) died during the immediate postoperative due to surgical complications. Of the remaining 45, 5 cases were lost to follow-up; 31 (63.26%) died (all of them as a result of the tumour (M+)); whereas 9 (18.36%) are still alive and disease-free. Overall mean survival is 35.91% 10.3 months (4-65 months). Of them, 3 (13.6%) were lost while in poor performance status; 13 (59.09%) died for neoplasia-related causes (M+), and only one (4.5%) is alive and disease free. In this group, neoadjuvant chemotherapy was used in 10 cases, neoadjuvant radiotherapy in 4 and adjuvant radiotherapy in 5. Local relapse was seen in 8 (36.6%) cases. In our experience, a clear improvement in quality of live and mean survival at one year (up to 65 months) was noted in patients with Vesical Infiltrant Carcinoma and regional node affectation. Such situation encourages the use of radical surgery when faced, during surgical examination, with node infiltration by neoplastic cells.

[Neoplasms in kidney transplant patients].

Our service performed a total of 619 kidney transplants between February 1980 and March 1993. Among them, 41 new neoplasias (6.6%) were diagnosed. Most frequent tumour was epithelioma (25) with a presentation age lower than in the normal population. Amongst the remaining tumours (16), the occurrence of 2 lymphoma and 2 Kaposi's sarcoma should be emphasized, together with the fast evolution progression of the others. Using a multiple regression model, an analysis is made on the influence certain factors have in the development of neoplasias, age being selected as the only significant one. The relative risk transplanted subjects have of suffering some type of neoplasia compared with the normal population is 36.

[Antimicrobial prophylaxis in urologic endoscopic surgery: pefloxacin versus ceftriaxone].

Prospective, randomized study in 96 patients undergoing urologic endoscopic surgery to assess the efficacy of two antimicrobials, pefloxacin and ceftriaxone, in the prevention of urinary tract infections. The disease most frequently prompting surgery was vesical tumour and prostate adenoma. All patients had sterile pre-operative urine. Drugs were given endovenously two hours prior surgery in one single dose. Prophylactic efficacy was measured through urine culture before removal of the catheters. Incidence of bacteriuria greater than 100,000 colonies/ml was 20% for the pefloxacin group compared to 15.2% for ceftriaxone. These differences were not statistically significant (Squared-chi test). These results show that pefloxacin is as effective as ceftriaxone in the prophylaxis of endoscopic urological surgery. A single dose schedule was not entirely suitable to reduce post-operative bacteriuria.

[Idiopathic granulomatous orchitis].

Idiopathic granulomatous orchitis is a rare testicle lesion of unknown etiology. This paper illustrates 10 cases studying their presentation, location, ultrasound and histological diagnosis and therapy. A testicular injury background and self-immune reaction appear as likely causes of this entity. Differential diagnosis with testes malignant tumours can only be reached after orchiectomy and a subsequent histological examination.

[Renal sarcoma].

Among 322 cases of primary malignant renal tumours reviewed between 1969 and 1991, six were renal sarcoma (1.85%). They all presented earlier symptomatology which was not different from other renal tumours, and nephrectomy was performed in all cases, 5 of which died before 14 months. The histopathological diagnose showed two liposarcoma, two carcinosarcomas, all the others being fibrosarcomas.

[Priapism of low flow].

The results obtained after treating 13 patients with low flow priapism diagnosed by cavernous gasometry, penile ecodoppler and cavernosography are explained. Seven cases of priapism (53%) developed following intracavernous injection of vasoactive drugs and had a good response to aspiration lavage and alpha-agonist medication. None of the cases needed shunt technique to achieve detumescence and all showed good evolution with regard to the erectile function. Six cases of priapism (47%) were idiopathic and they all needed some type of venous by-pass. Later, only one had normal erections.
